For campers and caravans.
The solar controller is a special development for use in campers and caravans, and it is suitable for all types and makes of
lead batteries (also for acid, GEL/dryfit, AGM/fleece batteries). Optimum charging is ensured by an intelligent
microprocessor control with characteristic lines IU1oU2.
Working fully automatically and maintenance-free, the solar controller offers the following functions:
Battery Ports and Charging Programs:
Charging port leisure battery, depending on the type of battery, 3 charging programs selectable (see table 1):
Lead Battery:
a) "Liquid Acid/AGM1":
b) "AGM2":
c) "Gel":
Charging Port Starter Battery:
Separate auxiliary charging port with reduced charging current (12 V (0.8 A or 1.5 A) for support charging and trickle
charging of the vehicle's starter battery with overcharge protection in case of extended stop periods.
Further Characteristics of the Unit:
•
The charging voltage being free from peaks is controlled in such a way, that any overcharging of the batteries is
excluded.
• Two Battery Charging Ports: Automatic charging of the main battery or leisure battery. Support charging and trickle
charging of the vehicle's starter battery with overcharge protection.
• Unattended Charging: Standard protection against back discharge of battery (in case of insufficient solar power (such
as at twilight, at night etc.) and against overload and overheating.
•
Floating Operation: Observation of the characteristic lines of charging, even with simultaneous operation of
consumers being connected to the battery.
• Overcharge protection: Reduction of the charging current of the battery in case of excessive solar power and full
battery. Immediate recharging in case of power consumption to ensure always the best possible charging state of the
battery.
•
Characteristic Line of Charging "IU1oU2": A defined charging boost (U1) avoids harmful acid accumulation and
provides compensation charge to the individual battery cells. After that, automatic trickle charging (U2).
•
On-board Mains Suppression Filter: Integrated on-board mains suppression filter ensures unproblematic parallel
operation of the controller with other charging sources, wind- and petrol-driven generators, mains supply chargers,
dynamos etc. at one battery.
•
Connection for Temperature Sensor
case of low outside temperatures, full charging of the weaker battery is improved, and in case of summery
temperatures unnecessary battery gassing will be avoided.
This is highly recommended, if the battery is exposed to strong variations in temperature, such as in the motor
compartment.
• Charging Cable Compensation: Automatic compensation of voltage losses on the charging cables.
•
Measurement Output for EBL (Electroblock of the Vehicle): Allows convenient application of the (solar) current
display being installed in the electroblock for supervision of the solar system.
